Not quite blacking out, but still having serious problems with memory as a result of alcohol or drug intake.

Graying out is spotiness or haziness of working and short term memory.

Most commonly a result of smoking copious amounts of reefer, graying out makes time move much faster.
Saturday morning me and a crazy ass white chick smoked so much pot that I grayed out until 6pm that night.
